Answer:
Its the 2nd one
Step-by-step explanation:
Simplify the exponents and then multiply
7x/x-4 * x/x+7
mutiply the numerators together
(7x)(x)= 7x^ 2
mutiply the denominators together
(x-4)(x+7)
(x)(x)(7)(x)= x^2+7x
(-4)(x)(-4)(7)= -4x-28
x^2+7x-4x-28
x^2+3x-28
Answer:
7x^2/x^ 2+3x-28
22 is the answer to this math problem
Answer:
1.84
Step-by-step explanation:
The given arc is a part of a unit circle centered at origin.
The x-coordinate on the unit circle represent the cosine value and y-coordinate on the unit circle represent sine value.
So, for angle equal to °, the x coordinate represents °.
So, ° = 0.86
Similarly, the y-coordinate of angle y represent °.
So, ° = 0.98
Therefore, the value of ° + ° = 0.86 + 0.98 = 1.84.
